The domain is all the values of x which are covered by the function. In this case, the domain is x <= 0. The range is all the values of y that the function passes through, so in this case, the domain is y >= 0. The only correct statement among the choices is the second.
Answer:
The overall change is -2/6 cents.
Step-by-step explanation:
The overall change in the stock price would be the increase minus the decrease.
The increase is 1/2
The decease is 5/6
1/2 - 5/6 =
Change 1/2 to 3/6
3/6 - 5/6 =
simplify
-2/6

5x = number of buffets purchased.
6 = 3 * 2 (three friends bought 3 $2 drinks)
Answer:
21 hours
Step-by-step explanation:
You want to find x such that B(x) = 31. Fill in the value and solve.
... 31 = 1.33e^(0.15x)
... 31/1.33 = e^(0.15x) . . . . divide by 1.33
... ln(31/1.33) = 0.15x . . . . take the natural log
... ln(31/1.33)/0.15 = x ≈ 20.992 . . . . hours
After 21 hours, the concentration will be 31 M/mL.
